In January 2017, Cruz assaulted someone and received a one-day internal suspension. The school asked for a “threat assessment,” on him, the records indicate.

School officials can request that the district’s Psychological Services department do such assessments on students if they feel like the student is a danger to himself or others, a former school security official told the Sun Sentinel.

Cruz transferred out of Stoneman Douglas on Feb. 8, 2017, then bounced between three alternative schools, most recently Rock Island OCLC in Oakland Park.

On Valentine’s Day, Cruz, now 19, was not at the Oakland Park school, but instead returned to the Stoneman Douglas campus and fatally shot 17 people with an AR-15 rifle. He’s admitted guilt and could face the death penalty.

As early as 3 years old, Cruz was diagnosed as developmentally disabled, the school district documents state.

After attending Westglades Middle, he moved in February 2014 to Cross Creek, a Pompano Beach public school that offers a program for emotionally and behaviorally disabled children.

The FBI ignored a tip last month that said accused Parkland, Florida, school killer Nikolas Cruz was at risk of committing a school shooting and has opened an investigation into what went wrong, the agency said Friday.

State records from the Department of Children & Families show Cruz was afflicted with a brain disorder marked by bouts of hyperactivity and a difficultly paying attention. The 2016 records also show him struggling with autism and depression.

He took medicine and had counselors who worked with him in school and at his home, the records state.

Gordon Weekes, one of Broward County’s chief assistant public defenders, said although Cruz had a supportive mother, who died a few months ago, “he needed more.”

At one point, according to the 2016 state report, crisis workers from Henderson Behavioral Health, a major mental health center, were called to the high school and determined that Cruz was “not at risk to harm himself or others.”

Weekes said Henderson workers should have hospitalized Cruz at that point. He’d gotten into a fight, records show, around Sept. 20, 2016 and was suspended. A week later, the state received a report he was cutting his arms on Snapchat, a mobile application.

The Department of Children & Families, however, concluded that “no referrals or services were needed” for him.

“If someone would have caught it and acted on the red flags we not would be here today,” Weekes said. “There were tragic red flags, and they just didn’t catch them.”

DCF Secretary Mike Carroll on Saturday night issued a statement saying that mental health services and supports were in place for Cruz when the agency’s investigation closed. The state only investigates whether an adult is safe and has access to help.
